ELECTRIC COOLING UNITS

FEATURES/BENEFITS

• Efficient cooling using hermetic compressors.
• Full range of electric heat sizes available — exactly the right
size for your needs.
• Accessory hydronic glycol heating coils are available for unit
sizes 155-300.
• High reliability — non-corrosive condensate pans (036-150),
prepainted cabinets and primed interior panels, and all units
are fully protected by internal safeties.
• Quietest operation in the industry — all compressors
mounted on independent vibration isolators. Standard
belt-driven evaporator fan motors on all units (except
558F036-060).
• Ease of maintenance achieved by standard size filters, tool-
less filter access, simple compressor access, permanently
lubricated fan motors, optional disconnect switch, optional
115-v convenience outlet, and optional hinged access
panels.
• Perfect Humidity™ dehumidification package (not available
on 558F036-150 units). This factory-installed option im-
proves the dehumidification capability of the rooftop unit and
helps control humidity levels in the conditioned space.
BRYANT MEANS TOP QUALITY AND RELIABILITY — Each
component utilized in these units is designed and tested for a
minimum of 15 years operation under the harshest conditions.
Every unit is thoroughly run tested at the factory in each oper-
ating mode and evacuated prior to final charging. Every coil is
leak-tested with helium particles. Automated run testing allows
accurate impartial tests and measurements which are second
to none in the industry.

Each unit contains a factory printout indicating tested
pressures, amperages, dates, and inspectors, providing certifi-
cation of the unit's status at the time of manufacture.
Units are equipped with valuable safety controls designed to
monitor and protect the unit for life. The standard safeties
include:
• low-pressure/loss-of-charge switch
• high-pressure switch
• freeze-protection thermostat
• internal compressor overload
• exclusive Cycle-LOC™ circuit board that provides compres-
sor anti-cycling (except 558F036-150)
• refrigerant filter drier
The cabinet is constructed of galvanized steel, bonderized and
coated with a prepainted baked enamel finish. The paint finish
is a non-chalking type, and is capable of exceeding Federal
Test Method Standard No. 141 (Method 6061) 500-Hour Salt
Spray Test. In addition, all internal cabinet panel surfaces are
primed, allowing the entire unit to have a longer life and more
attractive appearance.
EASY MAINTENANCE AND INSTALLATION
All Units are Factory Shipped in the Vertical Discharge
Configuration for fit-up to standard roof curbs. (One acces-
sory curb fits sizes 036-072; accessory curbs fit sizes 090-150
and 155-300.) The contractor can order and install the roof
curbs early in the construction stage, before decisions on size
requirements have been made.
All Units Feature Roll-Formed Baserail design with forklift
slots on 3 sides of the unit and rigging holes for easier maneu-
vering and installation. Stretch-wrap packaging protects the
unit during shipment and storage.

  • Page 2: Indoor-Air Quality (Iaq)

    INDOOR-AIR QUALITY (IAQ) Bryant rooftop units utilize certain key features that assist in improving the quality of the building air. Sloped condensate pans eliminate possible biological growth in the rooftop unit. A face-split indoor coil design (all 090-300 size units) proves effective in additional moisture removal from the supply air.

    As the refrigerant leaves the evaporator, the refrigerant passes a subcooler control low-pressure switch (S-LPS1 for circuit 1 or S-LPS2 for circuit 2) in the suction line. This low-pressure switch will deactivate the Perfect Humidity™ package when the suction pressure reaches 60 psig. The subcooler control low- pressure switch is an added safety device to protect against evaporator coil freeze-up during low ambient operation.
